Abstract
A temperature sensor includes a protective tube made of metal, a sensor element including a thermosensitive body and a pair of conductive wires electrically connected to the thermosensitive body and accommodated in the protective tube, a first heat-resistant insulator for ensuring electrical insulation of the pair of conductive wires inside the protective tube, and a second heat-resistant insulator provided between the first heat-resistant insulator and the protective tube for ensuring electrical insulation between the conductive wires and the protective tube.
Claims10
A temperature sensor, comprising:
- a protective tube made of metal;
- a sensor element including a thermosensitive body and a pair of conductive wires electrically connected to the thermosensitive body and accommodated in the protective tube;
- a first heat-resistant insulator that electrically insulates the pair of conductive wires inside the protective tube;
- and
- a cylindrical second heat-resistant insulator made of solid glass and provided between the first heat-resistant insulator and the protective tube that electrically insulates the protective tube from the pair of conductive wires, wherein
- the sensor element further includes:
- a covering body covering a periphery of the thermosensitive body;
- and
- a support tube joined to an end portion of the covering body and having a higher mechanical strength than the covering body, and
- an end portion of the cylindrical second heat-resistant insulator is fitted to an outside of the support tube in a radial direction of the cylindrical second heat-resistant insulator.
